Independence Hub Shut-In Due To Leak, 1 To 4 Weeks To Fix

Independence Hub in the Gulf of Mexico has been shut-in because of a leak on the Independence Trail pipeline, said an Enterprise Products Partners spokesperson.

Rick Rainey of Enterprise told Rigzone that the company had determined a leak in one of the associated pipelines of Independence Hub resulted in the shut-in of the platform and the pipeline itself.

A press release issued by the company stated that "initial investigations indicate that the leak is originating from a stainless steel o-ring gasket located on the flex joint in approximately 85 feet of water."

Enterprise, the majority owner of the platform, is implementing a "plan of action" to correct the damage that has resulted in the leak, said Rainey.

The equipment and personnel required to repair the damage is expected to arrive in a matter of days, and repairs are expected to be completed within one to four weeks.

Despite the leak, Enterprise stated that there has been no environmental impact, and the appropriate regulatory agenciaes have been notified.

Anadarko Petroleum spokesperson John Christiansen said they shut-in the platform at 9:30 am on April 9 due to a potential leak. He said at that time the company deployed an ROV to determine the location of the problem area. Anadarko is the operator of the platform.

No injuries or fires were caused by the leak.

Located in 8,000 feet of water on Mississippi Canyon block 920, approximately 123 miles southeast of Biloxi, Miss., the Independence Hub is the deepest production platform ever installed and also is the world's largest offshore natural gas processing facility.

The Independence Hub is a 105-foot, deep-draft, semi-submersible platform with a two-level production deck. The natural gas processed through the Hub when operating at full capacity represents an increase of more than 10 percent in supplies from the Gulf of Mexico.
